Judging from the comments on my blog post from 2010(!), when they hear QList 
people first think std::list (ie. linked list). Then they see that there's also 
a QLinkedList and start thinking that QList is something like std::deque. And 
then, if they are lucky, they realise it isn't that, either. Because both of 
those std containers guarantee stability of references under appends, as does 
QList _by default_.

Tell that to the authors of QToolBox and QDataWidgetMapper (off the top of my 
head). Better yet: put code where your mouth is and fix that blatant API abuse. 
I'll be more than happy to give you a +2 on that one.

And this is where I stop taking you seriously, sorry. You can demand such 
nonsense, but if you do, _do_ the work yourself. Go. Implement those 80+ 
algorithms from the STL for Qt. Or play god deciding which are the ones "no-
one will ever need" or "should never use" - IYHO.
